I did this race two times.
The first time was with the RX-Vision with a combination of maps 3, 4, 5 & 6.
I screwed up early on saw a band of rain, thought it would turn out to be heavy.
I lost on at one, ended up dropping down the order, finished 14th.
Did it with the BRZ GT300 and won it, was driving when I noticed it started to rain(had MFD on fuel map) saw the weather radar, big big rain cell.
Since I was on the back straight at the time, I drove into pit, put on wets,
Clawed my way up to first.
Then it started to dry up later on.
I had 3 laps of fuel left and my wets were gone. was thinking, I will go for 3 more laps then I will switch to wets
But understeered on the S bends before the back straight.
The AI were 1.5 seconds away that this point.
Switched over to the radar noticed another rain cell approaching.
I took a gamble and went for Wets, as if I went for inters all it would take is a few dark blue spots to put me into the wall.
My gamble paid off, since it was 16min left which is about 8 laps of fuel, I decided to add 10 laps and use fuel map 1 so I could gain back any time lost and then some.
The AI also enter at the same time, they switch to slicks which was a bullet to the head for them.
The BRZ GT300 makes it rather easy to win as its an easy to drive car in the wet or dry.
Did it in 917 living legend. Whole race on map 6 with one lap on RH in heavy rain (lost 50s) still ended up 30s in front.
I tried it with this car, it was too thirsty even on map 6.
Could've been my setup, though.
But I was pitting at the end of lap 6 and not gaining any real ground.
